!Undertaker!: Unfortunately it really seems that Ustica has very poor knowledge about endgames in this checkers variant which really surprises me ...
In every checkers club even small children are taught that ending of 3 queens vs 1 queen where the weaker side controls the main diagonal a1-h8 is a draw (except from several pathological cases of course ...). Ustica's ignorance of this simple fact is really surprising! :-)))
